Polymerization of Ethylene Catalyzed by TiCl4/Ni(acac)2 Supported Complex Catalysts
Abstract:
The TiCl4/Ni(acac)2 complex catalysts were prepared.The effects of SiCl4 and polymerization conditions on the polymerization of ethylene and their apparent kinetics parameters have been studied.The products obtained were characterized by DSC, IR and 13C NMR.The results indicated that SiCl4 could increase the catalytic activity of the catalysts and the polymer obtained have low melting temperatures, crystallinity, density and some branches.The complex catalysts have the function of oligomerization and in situ copolymerization for ethylene.
